One of the natural gas advantages, as primary energy source, is the opportunity to store it in large volumes under the same state as it is used by the final customers, without being subject to any state modification or conversion in another energy type. Gas depleted reservoirs are the first candidates for turning into underground storages, as the storage process is closest to the production process, but also due to the availability of a large amount of data which makes the reservoir to be well defined and also due...

Gas field redevelopments or rehabilitation projects have become an alternative approach to develop incremental production and additional reserves using new fit-for-purpose technology and concepts. The integrated reservoir study begins with geological characterization and modeling followed by evaluation of the geological gas resources and reserves considering the actual production profile. The redevelopment plan continues with a well by well review and nodal production system analysis to evaluate well performance a...

Hydrocarbon producing companies are looking at recovery factor evolution and replacement ratio of reserves as they are critical indicators for investments. Subsequently, these factors impact the business development process and the profitability. Maximizing the recovery factor means to have a detailed knowledge about the geological model and drive mechanism of the gas reservoir, especially when hydrocarbon production contains significant residual water which is driven up the well with the hydrocarbons. Replacement...
